BEEVILLE — A 35-year-old Beeville man sentenced to a 50-year prison term on Aug. 30 faces another 20 years behind bars if he is convicted on either of two counts of obstruction.

Billy Dean Butler was named in a two-count indictment on the charges when the Bee County Grand Jury met on Sept. 6.

According to the indictment, Butler threatened his girlfriend, the victim in the kidnapping case that sent him to prison two weeks ago.

The indictment alleged that Butler threatened to knock the woman’s teeth down her throat and threatened to kill her during an incident on Aug. 23, 2011. The threats allegedly were made in an attempt to keep the woman from testifying during the upcoming kidnapping trial, according to the investigating officer, Detective Sgt. Art Gamez.

The Beeville Police Department investigator also was one of the prosecution’s main witnesses in the kidnapping trial.

The obstruction charges were enhanced to second degree felonies, because Butler had a previous felony conviction on a charge of aggravated assault with a deadly weapon on Sept. 20, 2000, in Nueces County.

District Judge Joel Johnson set bond on the indictment at $1 million.

Grand jurors also returned indictments on three Texas Department of Criminal Justice inmates during the Sept. 6 session.

Those included:

• Juan Castro on a charge of aggravated assault with serious bodily injury.

The charge was enhanced to a second degree felony because Castro had a previous felony conviction.

The recent incident allegedly took place at the William G. McConnell Unit. The defendant was said to have struck a man in the head with an unknown object.

Castro was serving time on two April 18, 2006, robbery convictions in Harris County at the time of the incident.

If convicted, Castro could be sentenced to 20 years in prison and fined $10,000.

Bond was $50,000.

• Quintroy Davis on a charge of possession of a controlled substance in a correctional facility, enhanced to a third degree felony.

A conviction on a third degree felony could result in a 10-year prison sentence and a $10,000 fine.

TDCJ investigators alleged that Davis had cocaine while incarcerated at the McConnell Unit on June 8, 2012.

Davis had three previous felony convictions, including one for robbery on Aug. 28, 2001, one for possession of cocaine with intent to deliver on Sept. 21, 2011, and one on Oct. 13, 2008, on a charge of felon in possession of a weapon.

All the convictions were in Harris County.

Bond was $25,000.

•Raul Anthony Marquez on a charge of having a prohibited item in a correctional facility.

The charge was enhanced to a third degree felony, because Marquez had been convicted on two counts of aggravated robbery in Harris County on Aug. 30, 2007.

Bond was $25,000.
